Application filed June 29, 1917. Serial No. 177,690.

CAR-ROOF.

1,2fi5"?39 Specification of Letters Patent.

To all whom it may concern:

Be it known that I, RICHARD W. BURNETT, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had therein to the accom panyiug drawings.

The invention relates to car-roofs of the type in which the roofing-sheets are arranged below the carlines and are provided with upstanding flanges housed and weatherproofed by said carlines, the subject matter being related to that of my co-pending application, Serial Number 177,689. The invention comprises the novel means of supporting the sheets as hereinafter set forth.

In the drawings:

Figure l is a cross-section. through a carline, showing portions of adjacent roofing sheets and the means for supporting the same;

Fig. 2 is an end elevation of the supporting clip detached;

Fig. 3 is a plan view; and

Fig. i is a side elevation thereof.

A is a carline of inverted channel form provided with laterally and outwardly extending flanges B at the base thereof. C are the roofing sheets arranged beneath the carline, having upstanding flanges D extending within the channel and terminating at their upper ends in laterally, outwardly extending and preferably slightly return bent portions E. To form a simple means of supporting the sheets I provide clips, preferably of the construction shown in Figs. 2 and 4, comprising a portion F for fitting against the under face of the top of the carline and depending portious'G at opposite ends terminating in laterally, inwardly extending portions H. There is also provided a portion I which extends centrally from one end of the clip. The clips thus formed are secured to the carlines, preferably by spot-welding the portion 1* to the upper portion of the carline or securing it by any other suitable means.

In assembling, the sheets are arranged beneath the carlines and the flanges D thereof are pressed upward, passing between the inwardly-extending portions H of the clip, and are then moved outward to engage the portions E with the portions H. The portion I is then bent downward to extend between the flanges D and to operate as a spacer which holds the laterally-extending portions E and H in engagement with each other. This will preclude the accidental disengagement of the sheets, but whenever it is desired to remove a sheet, by bending back the spacer port-ions I this may be readily accomplished.

What I claim as my invention is 1. In a card-00f, the combination with an inverted channel carline, of roofing sheets having upstanding flan es housed within the channel of the carline, said flanges terminating in laterally, outwardly extending portions, and a supporting clip secured within the carline having depending end portions terminating in laterally, inwardly extending portions for engaging and supporting the laterally, outwardly extending portions of the sheets, said clips being also provided with a portion bendable to extend between the flanges of said sheets and form a Spacer to retain the same in engagement with the clips.

2. In a car-roof the combination with an inverted channel carline, of roofing sheets having upstanding flanges housed within the channel of the carline, said flanges terminating in laterally, outwardly extending portions, and a supporting clip having a portion fitting against and attached to the top portion of the carline, depending portions adjacent to the opposite sides of the carline terminating in laterally, inwardly extending portions and a portion extending from the attachment portion of the clip centrally of the carline, the inwardly-extending portions of said clip forming supports with which the laterally-extending portions of the sheet flanges may be engaged, and the central portion of the clip being bendable downward to form a spacer between said flanges, retaining the same in engagement with their supports.

3. In a car roof, the combination with a carline of inverted channel section of roofing sheets having upstanding flanges housed within the channel of the oarline, said flanges terminating in laterally, outwardly extending portions, and a clip for supporting said flanges comprising a portion fitting against the upper part of the carline and spot-welded thereto, depending portions adjacent to the opposite sides of the carline terminating in laterally, inwardly extending portions forming supports with which of the the outwardlyextemhng gm'tinne sheet flanges may he engaged, 11' Mon progec'tmg from l inverted channel car i116 of roofing k: 1 havmg upsmhdmg flanges housec said carhne, and means permzmemh' at tached to and can-hue mthm the c- .nel rhereoi 1'01 engaging sand flanges t0 suppolt the sheets.

Copies of this patent may be attained for cents each. 0

a. In a cnvrmi the combination with a mfihe of "ll'wevted channel section, of r001 in sheets having upsi'enchng flanges housed Within said on rhne. means permanently attached to the carline Within the channel thereof adapted for the detachable engagement of said fizm 'es therewith f0 support said sheeim and L! leans also vermanently attached. to the awhile for locking said flanges from ch senga gemeht.
